Watering

Keep soil slightly moist during active growth; avoid overwatering to prevent root rot

Fertilization

Diluted balanced liquid feed once monthly. Use low-nitrogen feed to promote flowering rather than excessive foliage growth

Eggshell powder topdress:Crush dried eggshells into fine powder; lightly mix into topsoil in early spring to add calcium without causing root burn
Pruning
  • Remove spent flower spikes after blooming to encourage self-seeding and maintain tidy growth
  • Trim dead or yellowing basal leaves in early spring to improve air circulation
  • Divide overcrowded clumps every 3–4 years in autumn to refresh root systems and promote vigor
